DBMS-specific enumeration overrides (plugins/dbms/<dbms>/enumeration.py),
driven through each full DBMS handler with the injection layer mocked, so the
dialect-specific table/column/user/privilege discovery paths run without a live
target, network, or DBMS. The in-band (UNION/error/direct) branch is taken via
conf.direct=True and inject.getValue is stubbed with canned result rows;
conf.batch=True avoids interactive prompts.

Consolidated from former tests/test_dbms_enum.py (Microsoft SQL Server),
tests/test_dbms_enum_a.py (Oracle/PostgreSQL/MySQL/SQLite) and
tests/test_dbms_enum_b.py (Sybase/MaxDB/MSSQL extra/DB2/Informix/Firebird/HSQLDB).

stdlib unittest only (no pytest / no pip); works on Python 2.7 and 3.x.
